Arch Linux 32bit, Stratagus V2.2.7, Aleona's Tales 2.2.7 R1
Some of these might be non-AT-related but rather Stratagus-related.

1. It seems like campaign progress doesn't get saved if the game crashes. I crashed the game in level 4 but only level 1 and 2 show up in Campaign Game/Frontier Force/ menu. To be most fair to players, the progress should be ideally saved the moment you see the "win" screen (or even shortly before?)

2. I saved in level 2 but loading that savegame crashes the game. A previous save in the same level works though.

1.
Campaign Progress is saved in preferences, at the end of the game in case of victory.
So it seems there is a bug.
You can manually change preferences.lua to fix your progress, (or use wargus cheat to pass the level).

2.
Already fixed in thunk.
bug happened when we load some dying units.

I would like to convey my appreciation for your kindness for men and women who actually need help on this important concept. Your real dedication to passing the solution all through had become extremely invaluable and has constantly permitted ladies just like me to reach their pursuits. Your own informative guideline entails so much to me and a whole lot more to my peers. Thank you; from each one of us.
